IMPRovl-:MENT IN CORN-PLANTERS.

Specification forming part of Letters Patent No. 154,347, dated August25, 1874; application filed June 29, 1874.

To all whom it may concern: v

Be it known that I, JAMES SELBY, of the city of Peoria, in the county ofPeoria, in the State of Illinois, have invented an Improve: ment inGorn-Droppers or Gut-Offs for (Jorn- Planters; and do hereby declarethat the following is a full, clear, and exactl description thereof,reference being had to the annexed drawings, making a part of thisspecication, in which like letters of reference refer to like parts, andin which- Figure l represents a plan view of upper surface of thecut-olf, and upon which the corn or seed lies; Fig. 2, a longitudinalsection of cut-olf and slide along dotted line a a, Fig. 1, which alsorepresents a longitudinal section of the adjoining valve-holes, &c., inthe other half of the cut-off and slide; Fig. 3, a view of the underside of the cut-0E, the slide removed; Fig. 4, a plan view of slide;Fig. 5, a

eross-section ofthe cut-off along line b b, Fig. 3; Fig. 6, across-section along line dd, Fig. 3; Fig. 7, a cross-section of slidealong line c c Fig. 7.

This invention relates to that class of droppers which have an upper andlower horizontal cut-off plate, two holes for the passage of I. corn,and a slide with a double-armed adjustable plate, which regulates thesize of the corn-passages.

My improvement consists in providing recessed spring cut-olf valves atthe head of the corn-passages, with a `stop or cross-piece extendingacross the neck of each valve,V behind the vibrating head e of the same,to prevent the friction of the head of the valve against the slide;also, in cutting away the inferior surface of the cut-off plate aroundthe recesses, which include the valves, for the purpose of doing awaywith that much extra friction; also, in the shape and arrangement ofthecorn-stirrers, which follow their respective corn-passages f in theslide, one stirrer being placed on each arm, and the cut-off plate abovecut away for the passage of the same back and forth.

In the drawings, A represents the cut-off plate, which forms the floorof the seed-box, a a representing the usualigcorn-passages, and e k e kthe valves, each of which has a flat oblong head, e, which playsvertically in a recess behind the arched end of the corn-pas-v sage a inthe cut-off plate, to which they are each riveted or screwed through theend of ktheir respective flat, spring-like stems k k. Across the neck ofeach valve, and forming a continuous flat surface with the inferior faceof the said cut-off plate is a stop or crosspiece, h, riveted or screwedin a recess for that purpose in said cut-off, for the purpose of keepingthe face or head e of the valve from rubbing upon the slide B B', butstill allowing the two to approach each other as near as may be withouttouching, to avoid friction. The corn-passages a a and the valves e k ek are surrounded, or partially so, with a depression, z z, &c., in thesurface of the cutoff plate A, (seen in profile in sections, Figs.

5 and\6,) in such a manner as toleavea rib or low wall round the valvesand corn-passages, the top of which is level with the general face ofthe plate. Bl represents vthe usual slide, and B the usual dou .armedcorn-passage adjuster. (Seen in pl the latter are provide projections dd, lying? on the surface of and parallel with each arm,each in a linewithv the corn-passages f j', and are intended to push or looseni thecorn about the holes, and may be attached to or made removable from theslide at convenience. Grooves b b are cut in the inferior surface of thecut-olf plate A, at each end of same, for the passage"`back and forth(with the slide) of the stirrers d d.

What I claim as my invention is- 1. A cut-off having the spring-valves ela e 7c embedded in its under side, with cross-pieces or detents h h onthe neck of each valve, and the depressions z z, 85o., around bothvalves and corn-passages a a, substantially as and for the purposesdescribed.

2. In combination with the valves e k .e k and the cut-olf A, thedetents h h, substantially as and for the purposes described.

3. A cut-off plate provided with grooves b b on its under surface,leading to each corn-passage and valve, for the reception and passageback and forth of the stirrers el d, attached to the slide below,substantially as and for the purposes described.

In testimony that I claim the foregoing cutolf for corn-planters, I havehereunto set my hand this 23d `day of June, A. D. 1874.
